Multiple SQL statements together?
I am testing each column in a table to see if it has null values. Currently, I am using:
select count (column) when column is not null
I have a list of 20 of these for each column. Can I combine them all to run it once and then tell me the record count for each column. Any column that has 0 would be a null column
The where clause is redundant. You can just add all to a single query:
select count(column1), count(column2), . . . count(column20) from t
